Spring-type straight pin (spiral pin) coiled, heavy duty ISO 8748 Spring steel 420-545 HV30

Article number
Material	Spring steel
Material technical	420-545 HV30
Info	Warning: electroplating of these products may cause hydrogen embrittlement. Dimensions d₁ and d₂ in above table are before mounting. V = minimum shear strength, double, in kN. The recommended tolerance class for the accommodating hole diameter d (nominal) is H12.Special features of coiled spring-type straight pins (spiral pins): These pins are used for connections or the positioning of two or more parts and may also be used as shafts and hinge-, stop- or carrierpins, and are easily disassembled. Thanks to their spiral shaped cross section (approximately 2.1/4 coils) these pins are very flexible and suitable for repeated use with dynamic loads. Equal stress distribution throughout their cross section against the hole wall produces a good press fit, which can absorb shear forces unaffected by the direction. The pins are chamfered at both ends, so they can easily be inserted and installed automatically.
